Venom, or the Venom Symbiote, is a symboite of life form in the Marvic comic universe. The creature is a sentient alien with a gooey, almost liquid-like form. It requires a host, usually human, to bond around for its survival. In return the Venom creature gives its host enhanced powers. In effect, when the Venom Symbiote bonds with a human to form a super-villain, that new dual-life form itself is also often called Venom. Its second host Eddie Brock after bonding with the symbiote to become the first Venom, is one of spider-mans archenemies. Spider-Man was the first host it merged with before its evil motives were clear. After Spider-Man rejected it, the symbiote went on to merge with other hosts (starting with the most famous Venom: Eddie Brock) and so began its reign as the villain known as Venom. Comics journalist and historian Mike Conroy writes of the character: "What started out as a replacement costume for Spider-Man turned into one of the Marvel web-slinger's greatest nightmares."
Venom has become one of Spider-Man's most enduring and popular foes. Indeed, he has become so popular that he is seen as Spider-Man's arch-nemesis, in terms of his popularity. Venom was ranked as the 22nd Greatest Comic Book Villain of All Time in IGN's list of the top 100 comic villains, 67th Greatest Villain of all time in Wizard Magazine's Top 100 Greatest Villains Ever list,and was ranked as the 98th Greatest Comic Book Character Ever in Wizard Magazine's 200 Greatest Comic Book Characters of all Time list. Contrary to popular belief, the idea for the Venom symbiote was not originally thought up by artists Mike Zeck and Todd McFarlane or writer Dave Micheline, but by a Marvel Comics reader from Norridge, Illinois named Randy Schueller. Marvel bought the idea for $220.00 and the current editor in chief at the time, Jim Shooter, sent Schueller a letter acknowledging Marvel's desire to purchase the idea from him
